4 Claims.

This invention relates to sterilizing devices and more particularly to asterilizing device wherein the articles placed therein may be easily andreadily removed therefrom.

An object of this invention is to provide a sterilizer which is soconstructed that a sterilizing liquid can be placed within the deviceand articles immersed in the liquid and at the same time articlessupported above the liquid in a drying posi-V 10 tion.

A further object of this invention is to provide a sterilizer of thiskind which is so constructed that it will comply with all of therequirements of the various boards of health in the locality in 15 whichthe device is used and which at the same time embodies means for readilysupporting the articles in the sterilizing fluid, the device includingmeans whereby the articles may be readily withdrawn without insertingthe hands or any im- 20 plements `in the sterilizing fluid.

The above and various other objects and aclvantages of this inventionwill in part be described in and in part be understood from thefollowing detailed description of the present pre- 25 ferred embodiment,the same being illustrated in the accompanying drawings, wherein:-

Figure 1 is a longitudinal section taken substantially through thecenter of a device constructed according to the preferred embodiment 3oof this invention;

Figure 2 is a fragmentary on the line 2-2 of Figure l;

Figure 3 is a transverse sectional view taken on the line 3-3 of Figurel;

Figure 4 is a fragmentary perspective view of the front portion of theupper tray;

Figure 5 is a fragmentary perspective view of the rear portion of theupper tray, and

Figure 6 is a fragmentary perspective view of sectional view taken @lothe rear portion of the lower tray.

Referring to the drawings wherein like numerals of reference designatecorresponding parts throughout the several views, the numeral 10designates generally a receptacle or liquid con- 15 tainer which may beconstructed of suitable inaterial such as glass, porcelain, metal or thelike.

The container 10 has an open top and a forwardly and upwardly inclinedfront wall 11. Preferably this container 10 is constructed of 'QQ glasssuitably treated so as to make it substantially unbreakable.

A lid 12 engages the upper end of the receptacle 10 and is provided atthe sides thereof with depending flanges 13 which closely engage theside 55." Walls of the container 10 so that the cover or closure 12snugly fits on the top of the receptacle 10. By providing theseoverlapping flanges 13, no dirt or dust particles can enter the interiorof the receptacle 10 when the lid 12 is in closed position. The 'rearend of the lid 12 is provided with a U- shaped hinge member 14 which Yisintegrally formed with the lid 12, this hinge member 14 being soconstructed as to permit the swinging upward movement of the lid 12 atthe rear wall of the container l0, While permitting the ready withdrawalof the lid 12 with the attachments hereinafter described, from theinterior of the container 10.

Disposed within the container 10 there is an article supporting tray ormember, generally designated as 15, which is constructed of perforatematerial in the form of wire mesh or the like, this tray 15 having abottom 16, side walls 17, and a rear wall 18, which rear wall extendsupwardly above the top of the sidewalls 17. In order to properly supportthe tray 15 within the interior of the container 10, we have provided apair of depending looped strap members 19, which are secured to theinner face of the lid 12, these loop members 19 being secured in spacedrelation to each other so as to properly support the tray 15 in aposition above the bottom of the container 10 and inwardly of each sidewall of the container. The front end of the trayA 15 is preferably openso as to permit the ready positioning of articles or tools therein andto also permit the ready withdrawal of these tools whenthe lid 12 israised upwardly by grasping the handle or tongue 20 which extendsforwardly from the forward edge of the lid.

An upper tray generally designated as 21 is supported within thesupporting straps 19 in a position Where the bottom 22 thereof will benormally out of the liquid which is used for sterilizing the tools orarticles in the lower tray 15 so 95 that these tools may be withdrawnfrom the lower 1' tray and placed into the upper tray for drying. Thetray 21 has adjacent its forward or front edge depending flanges 23which engage over the upper edge of the side walls 17 of the lower tray15 and the side walls 24 of the upper tray 21 terminate inwardly of therear end of the bottom 22 and are provided with a slit 25 so that theinner end of these side members 24 can overlap the up- Wardly extendingside wall portions 26 of the lower tray side Walls 17.

In the use of this device the desired sterilizing fluid may be placedwithin the tray or receptacle 10 to the desired depth and the articlesin the form of tools or the like placed in the lower 1410 tray 15. Thelid 12 may then be placed over the open end of the receptacle 10 so asto suspend the tray 15 within the fluid and immerse the tools therein.When these tools have been properly sterilized they may be withdrawn bylifting up the forward end of the lid by grasping the tongue 20 andraising the forward end of the lid 12y with the U-'shaped hinge member14 Aas a fulcrum. The sterilized tools may be placed in theY upper tray21 which will be normally out of the uid and the lid 12 again closedthereby preventing dust particles or germs from accumulating on 'thesterilized tools.

By providing the lower tray 15 with the upwardly extending upwardlywithout having the tools mounted in the lower tray 15 or in theupper-tray 21 slide against the rear wall of the container 10. Byconstructing the trays 15 and 21 in superposedpositionv any desirednumber of trays may be placed within the hangers or supporting members'19 depending only upon the'depth of the container 10 and the depth ofthe hangers or supporting members 19. The draining member or tray 21 isslidably mounted on the upper edge of the tray 15, this beingaccomplished by extending the sides of the tray 21 adjacent the frontend thereof, as at 23, outwardly and downwardly over the upper frontedges of the lower tray 15 and the rear end of the draining tray 21 isprovided with a slot 25 which receives the rear edge 26 of the lowertray 15 and the opposite edges of the draining' tray 21 rest on top ofthe lower tray at these points. In this manner, the upper tray 21 can bereadily removed when desired, either with or without the removal of thelower tray 15.

It is, of course, understood that various changes and'modiiications maybe made in the details of construction and design of the abovespecifically described embodiment of this invention without departingfrom the spirit thereof, such changes and modifications being restrictedonly by the scope of the following claims.
